  • danfoss - pressure independent balancing & control valves
  • Pressure Independent Balancing & Control Valves (PIBCV) represent the latest development in balancing and control solutions. Successfully introduced by Danfoss, they have become a standard in many heating and cooling systems offering the lowest possible “Total Cost of Ownership”. Combining the control function, pressure independency and flow limitation all in one valve saves in purchasing individual valves and reduces valuable time. Visit the website or contact SAI for more information.

top ten product for 2018:

SEMCO's 3fficiency system was recognized as one of the Top 10 Green Building Products for 2018 by BuildingGreen at the annual Greenbuild Expo. BuildingGreen, an unbiased resource for sustainable building strategies, has been recognizing products that promote green design and architecture through its Top 10 Awards since 2001. The selections are announced at Greenbuild Expo, the world's largest conference focused on green building practices.

3fficiency is the HVAC industry's first total indoor air quality (IAQ) system approach to chilled beam design and it suprasses the ASHRAE 90.1 energy standard by up to 30%.
"BuildingGreen has long recognized the energy and space-saving benefits of active chilled beams, but they could be a challenge to specify due to potential problems with humidity and comfort," Brent Ehrlich, Products & Materials specialist at BuildingGreen, said. "By combining SEMCO's active chilled beams, NEUTON control module, and Pinnacle dedicated outdoor air system into one system, SEMCO's 3fficiency system provides critical humidity controls and the ability to heat and cool different zones in a package that is easier to install and commission."

Since 3fficiency uses water rather than refrigerant, many restrictions and concerns regarding refrigerant usage can be avoided. Thousands of dollars in installation costs (compared to VRF installations) can be realized as well. more
